For most of our products there is a 2:1 relationship between IT and IH. For some products this can be as low as 1.7:1 and for others as great as 3:1. The material and manufacturing variances in resistance as well as the change of resistance after a trip event or high temperature installation will determine the ratio of IT to IH. For most of our products this makes the 2:1 ratio the most practical value.
